Question

the sum of three consecutive multiples of 5 is 180 find the numbers

Answer 1

Answer:

Let the three consecutive number be x, x+5 , x+5+5

sum=180 ( given)

ATQ,

=> x + (x+5) + (x+10)=180

=> x + x + 5 + x + 10 =180

=> 3x + 15 = 180

=> 3x = 180-15

=> 3x = 165

=> x = 165÷3

=> x = 55.

Thus the consecutive multiples of 5 that sum upto 180 are:

x=55,

x+5 =55+5 = 60

x+10=55+10=65.
